> How many terrible teachers are allowed to continue to teach after decades of disastrous results?

Counterpoint: Why "hire" a known-bad teacher? Is a teacher that is known to give fake information better or worse than none at all?

I don't know the answer to this, but I hope that Khan Academy thought about this and decided that the good of GPT is better than it's bad. Or, they can't know so thats why they're doing a limited study before rolling this out.
